CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119 from Korean Patent Application No. 10-2011-0071622, filed on Jul. 19, 2011, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

1. Field

The present general inventive concept relates to a host device, a managing server, and a method of controlling image formation thereof, and more particularly, to a host device and a managing server which are operated in a managed printing and service or solution (MPS) system environment, and a method of controlling image formation thereof.

2. Description of the Related Art

A conventional image forming apparatus prints print data generated in a terminal apparatus, such as a computer, on recording paper. Examples of such an image forming apparatus are copiers, printers, facsimile machines, or multifunction peripherals (MFP) that include functions of all the aforementioned devices in a single device.

Recently, public offices, universities, or companies provide a managing system such as a managed printing and service or solution (MPS) system to facilitate management of numerous image forming apparatuses.

The MPS system refers to a system that manages printers or MFPs in a network and a job (print, copy, fax, or scan) log thereof and processes business logic such as usage and corresponding charges on an individual or group basis through job accounting (JAC).

However, in a related-art method, an administrator may desire to add a plurality of users corresponding to each image forming apparatus directly via the MPS system for the JAC. In other words, the administrator would be required to conduct a preliminary search regarding who will use each image forming apparatus from the plurality of users.

Accordingly, it also is necessary to conduct a preliminary search on which department will be allocated each of the printers and which user will be allocated each of the printers. That is, actual users of each printer should be determined.

Further, the administrator should individually register the users who have been determined to be allocated each printer in the system, and should repeat the work to register, as the number of users and the number of printers increase.

Also, if there is a change in a personnel structure in a department or if a user desires to use a different printer other than the printer assigned to her/him due to a temporary problem of the printer, the administrator should be able reflect these changes to the system every time that the changes occur.

This is because CLX-9250 9350 Series and SCX-6X55 Series have been selected and used. If CLX-8385 series and CLP-660 in which the JAC is not set are selected and an OK button is pressed in this state as illustrated in FIG. 4F, the host device 100 requests the managing server 200 to set the authority for the selected printers, and, if the request is permitted, the JAC setting information is changed to ‘Set’.

If the user moves a different network environment from an already used network environment for any reason while using the application, the user may search printers connected to the host device 100 manually or automatically as illustrated in FIG. 4G. In this case, printers that are searched in the new network environment may be used and displayed as illustrated in FIG. 4H.

If the host device 100 requests the managing server 200 to set the authority corresponding to printers (SCX-1385 Series and SCX-2X55) corresponding to information corresponding to the printers selected as illustrated in FIG. 4H, the managing server 200 determines whether the user has the authority use the selected printers. The authority is determined by comparing the user information with authority information corresponding to each printer stored in the managing server 200 as illustrated in FIG. 4I. The authority information corresponding to each printer may be modified through the user interface. As illustrated in FIG. 4I, the authority information corresponding to each printer is stored separately according to each printer. If the user of the host device 100 selects SCX-1385 Series by setting the JAC, the managing server 200 determines whether the user of the host device has the authority to access the printer. For example, if the user is neither ‘King Sejong’ nor ‘Design Group 1’, the user is not permitted to use the printer SCX-138 Series and the authority is not permitted. In the case that the printer CXL-9250 9350 Series are permissible for all of the users and all of the groups, if the user of the host device 100 selects the printer CLX-9250 9350 Series by setting the JAC, the authority is permitted and printing is performed using CLX-9250 9350 Series.

FIG. 4J is a view illustrating a screen to notify the host device 100 whether the user has the authority to use the selected printers, if CLX-9250 9350 Series and SCX-6X55 Series are selected. It can be seen that CLX-9250 9350 Series has succeeded and SCX-6X55 Series has failed. Here, the JAC setting information indicates that the JAC for CLX-9250 9350 Series is set.

As illustrated in FIGS. 4A through 4J, the application periodically monitors a list of printers selected by the user, and transmits the information on the selected printers and the user information at the time that the printer is initially selected and every time that changes occur. If the JAC setting corresponding to the selected printer is completed based on the information received by the managing server 200, the user prints using the printer in which the JAC is set.

FIGS. 5A through 5E are views illustrating an operational characteristic of the managing server of FIG. 3.

In FIGS. 5A through 5E, the image forming apparatus 300 will be described as a printer. However, this should not be considered as limiting and any image forming apparatus can be applied.

The managing server 200 is associated with the user information database (for example, an LDAP) and thus is periodically updated, if a user is added, deleted, or changed.

FIG. 5A is a view displaying user information periodically updated by the managing server 200. As illustrated in FIG. 5A, in the case that user “Gil Dong HONG” is registered as a user, if user ‘Gil Dong HONG’ resigns or moves to a different department, the managing server 200 removes ‘Gil Dong HONG’ from the user information or changes his department automatically in association with the user information database.

The managing server 200 may receive user information and information on a selected printer from the host device 100, and determines whether the user has the authority to use the selected printer.

If the authority is permitted, user information is added and stored with reference to the printer in relation to the user authority corresponding to each printer. Also, if the user information of the printer is changed, the corresponding user information is updated.

FIG. 5B is a view displaying the user information and the information on the selected printer transmitted from the host device 100. FIG. 5B illustrates that ‘Chul Soo KIM’ is the user information and ‘CLX-8385 Series and CLP-660’ is the information on the selected printer, which are transmitted to the managing server.

FIG. 5C is a view displaying user authority information corresponding to each printer stored in the storage unit of the managing server 200. If the authority corresponding to the printers selected by ‘Chul Soo KIM’ and ‘Gil Dong HONG’ is permitted based on the information illustrated in FIG. 5B, the user authority information corresponding to each printer stored in the storage unit of the managing server 200 is illustrated in FIG. 5C. Since ‘Chul Soo KIM’ selects ‘CLX-8385 Series’ and ‘CLP-660’, ‘Chul Soo KIM’ is added to ‘CLX-8385 Series’ and stored, and ‘Chul Soo KIM’ is also added to ‘CLP-660’ and stored. That is, the managing server 200 adds the user separately according to each printer and stores the user.

FIG. 5D is a view illustrating how the storage unit is updated, if the user authority information corresponding to each printer is changed. It can be seen from FIG. 5D that ‘Gil Dong HONG’ is added to ‘CLP-660’. This means that ‘Gil Dong HONG’ selects ‘CLP-660’ through the host device 100 and the managing server 200 confirms that there is user information of ‘Gil Dong HONG’ and ‘Gil Dong HONG’ has the authority to use ‘CLP-660’ and thus update the storage unit by adding ‘Gil Dong HONG.’

FIG. 5E illustrates quarter values of users corresponding to each printer. In FIG. 5E, ‘U’ means a unlimited quarter value and thus ‘Gil Dong HONG’ can use print, copy, fax, and scan without limit.

FIG. 6 is a flowchart illustrating a method of controlling image formation of a host device according to an exemplary embodiment of the present general inventive concept.

Referring to FIG. 6, a user inputs user information to log in a managing server at operation S610. Accordingly, a user interface window may be displayed as illustrated in FIG. 4B.

The input user information is transmitted to the managing server at operation S620. If the login to the managing server is performed, information corresponding to an image forming apparatus connected to a host device may be displayed at operation S630. In this case, the information on the image forming apparatus connected to the host device is searched as illustrated in FIG. 4C, and, if a selecting menu is selected, the user interface window illustrated in FIG. 4D is displayed.

If at least one image forming apparatus is selected from the displayed information corresponding to the image forming apparatus at operation S640: Y, information corresponding to the selected image forming apparatus and the user information are transmitted to the managing server at operation S650. If the at least one image forming apparatus is not selected from the displayed information corresponding to the image forming apparatus at operation S640: N, the information corresponding to the image forming apparatus and the user information are not transmitted to the managing server.

FIG. 7 is a flowchart illustrating a method of controlling image formation of a managing server according to an exemplary embodiment.

Referring to FIG. 7, the managing server receives user information from the user information database at operation S710. Already stored user information and authority information corresponding to each image forming apparatus are periodically updated according to the received information at operation S720. The managing server receives user information input through a host device and information corresponding to at least one image forming apparatus selected by the host device at operation S730. The managing server compares the received information and the updated information and determines whether a user of the host device has the authority to use the host device at operation S740.

If the authority of the user of the host device is permitted at operation S750: Y, the managing server notifies the host device and the image forming apparatus of permission of the use at operation S760. The updated information is automatically updated according to the received information at operation S770.

If the authority of the user of the host device is not permitted at operation S750: N, the managing server notifies the host device and the image forming apparatus of non-permission of the use at operation S780.

As described above, according to the various exemplary embodiments, a real user can be automatically added or set for a plurality of printers without intervention by an administrator in an MPS system environment.

Also, if an organization is changed and thus a printing environment of a user is changed, JAC setting can be achieved or released without intervention by an administrator.

If a user is added or removed, JAC setting can be actively achieved without intervention by an administrator.

The present general inventive concept can also be embodied as computer-readable codes on a computer-readable medium. The computer-readable medium can include a computer-readable recording medium and a computer-readable transmission medium. The computer-readable recording medium is any data storage device that can store data as a program which can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, DVDs, magnetic tapes, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. The computer-readable transmission medium can generate or transmit carrier waves or signals (e.g., wired or wireless data transmission through the Internet). Also, functional programs, codes, and code segments to accomplish the present general inventive concept can be easily construed by programmers skilled in the art to which the present general inventive concept pertains
